Bryan Johnson, the tech entrepreneur who has spent millions attempting to reverse aging through extreme medical protocols, now says he may have pushed his longevity experiments too far. The admission comes after a year marked by an autoimmune diagnosis and experimental drug use, raising questions about the limits of biohacking.
Second Thoughts on Radical Experiments
Johnson posted his doubts on social media Thursday, telling followers he has been thinking things over about his famous antiaging crusade. The statement shocked many observers, given his unwavering commitment to Project Blueprint since 2021. The tech millionaire, who sold his payments company Braintree for millions, has become known for transforming his body into what he calls the most biologically measured person in history.
Just one day before expressing doubts, Johnson claimed people may eventually live to be 500 years old. The dramatic reversal in tone led some followers to question whether his account had been compromised. His extensive protocol includes strict bedtimes, controlled diets, daily exercise, supplements, prescription medications, frequent bloodwork and scans, plus a team of doctors monitoring his every vital sign around the clock.
Autoimmune Disease and Mushroom Experiments
Earlier this month, Johnson revealed doctors diagnosed him with gastritis, an autoimmune condition where the immune system attacks stomach lining. The diagnosis came despite years of extensive health testing that failed to detect the condition. Johnson announced plans to reverse what medical professionals consider an incurable disease, demonstrating his continued defiance of conventional medical wisdom.
Johnson also experimented twice with psilocybin mushrooms this year, livestreaming himself taking nearly five grams of the hallucinogenic substance. After analyzing data from the experience, he claimed the mushrooms present a compelling case for longevity potential. Johnson said psilocybin calmed both his body and mind, though the drug remains federally illegal for recreational use in most states.
Criticizing Silicon Valley Health Culture
Speaking at a Business Insider event in April, Johnson criticized Silicon Valley founders who embrace what he calls monk mode culture. He targeted entrepreneurs who claim they will avoid dating until reaching business milestones like Series B funding rounds. Johnson argued that founders who neglect their health produce what he termed poor quality work, comparing unhealthy bodies to defective computer code.
His advice for living longer includes avoiding alcohol entirely and maintaining an active intimate life. The protocol represents a significant financial commitment, with Johnson spending millions annually on his regimented antiaging program since officially launching Project Blueprint in 2021. Whether his recent doubts signal a major shift in approach or temporary reflection remains unclear.
